Ningbo Fangli Technology Co., Ltd. is a mechanical equipment manufacturer with nearly 30 years’ experiences of plastic pipe extrusion equipment, new environmental protection and new materials equipment. Since its establishment Fangli has been developed based on user’s demands. Through continuous improvement, independent R&D on the core technology and digestion & absorption of advanced technology and other means, we have developed PVC pipe extrusion line, PP-R pipe extrusion line, PE water supply / gas pipe extrusion line, which was recommended by the Chinese Ministry of Construction to replace imported products. We have gained the title of “First-class Brand in Zhejiang Province”.
The Chinese name of HDPE pipe produced by HDPE pipe production line is high-density polyethylene pipe. It is a thermoplastic resin pipe with high crystallinity and non polarity, and a thermoplastic resin with high crystallinity and non-polarity.
HDPE (high density polyethylene) plastic pipe is developing steadily, of which water supply pipe and gas pipe are its two larger application markets.
HDPE pipe shall not only have good economy, but also have a series of advantages such as stable and reliable interface, impact resistance, cracking resistance, aging resistance, corrosion resistance and so on:
·Reliable connection: polyethylene pipe systems are connected by electrothermal fusion, and the strength of the joint is higher than that of the pipe body.
·Good low-temperature impact resistance: the low-temperature embrittlement temperature of polyethylene is very low, and it can be used safely in the temperature range of - 60-60 ℃. During construction in winter, due to the good impact resistance of the material, pipe embrittlement will not occur.
·Good stress cracking resistance: HDPE has low notch sensitivity, high shear strength and excellent scratch resistance, and its environmental stress cracking resistance is also very outstanding.
·Good chemical corrosion resistance: HDPE pipeline can resist the corrosion of a variety of chemical media, and the chemicals in the soil will not cause any degradation to the pipeline. Polyethylene is the insulator of electricity, so it will not rot, rust or electrochemical corrosion; In addition, it does not promote the growth of algae, bacteria or fungi.
Precautions for ordinary use of HDPE pipes produced by HDPE pipe production line:
1. Outdoor laying in the open air, where there is sunlight, it is recommended to take shielding measures;
2. Buried HDPE water supply pipeline can resist thermal stress without reserving pipe length; in winter, there is no need to reserve pipe length;
3. When installing HDPE pipes, if the operation space is too small, electrofusion connection shall be adopted;
4. When reworking, the welding angle of the socket and spigot shall not be too high, and the welding temperature shall not be controlled at the same time;
5. During hot-melt butt connection, the voltage shall be between 200-220v, and the heating shall be moderate to avoid false welding.
